I dip my chrome emblems, radio knobs,Rallye lug nuts, hood pins or just about anything chrome that looks pit free but grungy in this. It does an awesome job of cleaning off decades of crap on emblems. I use a soft toothbrush to gently scrub the parts before rinsing off with water. Even the plastic style radio knobs with the chrome on the edges come out looking incredible with just a little brushing and a rinse. I do not leave those in there for more than a few minutes as it will remove the chrome if left submerged for too long.
